927 F.3d 1292
Fed. Cir.2019Background
- Elbit sued Hughes alleging infringement of U.S. Patent No. 6,240,073 (reverse-link satellite communications). Jury found Hughes infringed claims 2–4 of the ’073 patent and awarded $21,075,750; no appeal by Elbit on the separate ’874 patent finding.
- Key claim elements at issue were means-plus-function terms: a “second communication means for continuous transmission of data” and a “switching means” (structure construed to a channel-assignment transmitter and a modem/driver implementing specified algorithms).
- Accused Hughes products (DirecWay, HN, HX, Jupiter) use two transmission modes: ALOHA (short bursts) and Dynamic Stream (variable/longer transmissions); Hughes argued guard times/interruptions preclude “continuous transmission.”
- Dispute over whether Hughes’s system implements the patent’s switching algorithm and whether the terminal (not just the hub) controls switching and requests a specific data rate.
- Damages expert relied on a prior settlement (Hughes–Gilat) as a comparable license, adjusted for two-way technology value; Hughes raised apportionment and prejudicial-revenue arguments but offered no damages expert.
- District court also found the case exceptional under 35 U.S.C. § 285 and awarded fees, but did not quantify them; appeal challenges infringement, damages, and exceptionality (unquantified-fees portion dismissed for lack of jurisdiction).
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether accused products include a “continuous transmission of data” communication means | Elbit: Dynamic Stream provides continuous transmission (variable-long transmissions) and transmits large files analogous to patent’s second means | Hughes: Dynamic Stream has guard times (interruptions) so it is not continuous | Court: Substantial evidence supported jury finding of continuous transmission (expert testimony + product docs); guard times did not negate continuity as a matter of law |
| Whether accused products implement the claimed switching means (including switching back and requesting a specific data rate) | Elbit: Evidence shows switching tied to message length/backlog, terminal controls backlog signaling, hub obeys it, and system requests slots/data rate equivalents | Hughes: Hub controls some switching; accused system does not follow the patent’s algorithm or request a specific rate | Court: Substantial evidence supported jury finding that terminal controls switching, that switching criteria (message length/backlog) are met, and that the system performs/request-equivalent data-rate functions |
| Whether the damages award (reasonable royalty) was supported and properly apportioned | Elbit: Used Hughes–Gilat settlement as comparable, adjusted for two-way value; expert accounted for differences and apportionment implicitly | Hughes: Settlement not comparable; failed apportionment; prejudicial reliance on revenue figures | Court: Denial of new trial not an abuse of discretion; comparable-license approach and adjustments were permissible and apportionment satisfied; revenue references not reversible error under the record |
| Whether appellate court has jurisdiction to review the district court’s finding of exceptionality (§ 285) before fees quantified | Elbit: Fee entitlement is not separately final until quantified | Hughes: Appealable under §1292(c)(2) or pendent jurisdiction | Court: No jurisdiction to review unquantified fee-entitlement ruling; appeal of exceptionality dismissed (finality and Budinich/Falana principles) |
